SPRING-MOTOR FANS.

It has for its object to provide a spring motor for'fans which can be operated with a very small amount of energy.

It further has for itsobjeot to provide a spring motor for fans which is simple, inexpensive and durable in construction', easy to operate, almost noiseless, convenient to use and which furnishes a maximum amount' of power with a minimum output or amount of energy.

It further has for its object to provide a motor Y. which can be operated without .the use of electricity, gas, gasolene, alcohol and the like and which can be conveniently transported to any place where it is desired to use the same.

My invention consists in the several features and in the construction, combination and arrangement' of features as more fully p hereinafter described and claimed.

Referring to the drawings l Figure 1 is -a front elevation of my invention.

Fig. 2 is a sideielevation with the casing shown in Section to clearly show the operative parts mounted therein.

Fig. 3 is a detail front view of one of the depending lugs of the casing.

Fig. 4 is a detail view of the brake Vlever and the securing means therefor.

In the drawings in which like reference characters denote like parts throughout the several views, 1 represents the casing inclosing the^ operative mechanism of the fan, which is provided with depending lugs 2 and 3 each provided with a hole 4 therethrough and the lug 2 being provided with a hole 5 just above the hole 4.

The casing is provided at the top with an Patented Feb. e, 1917.

Application led May 20, 1916. Serial No. 98,946.

upwardly extending hood or cap 6 in which, vthe, shaft carrying the fan is mounted as hereinafter described.

7 is the base on which the casing 1 is piv? otally mounted, by means of a pin 7al whlch in turn is mounted in the holes 4, to adapt the casing to be adjusted forwardly and rearwardly, and provided with an upwardly extendinglug 8 having a series of preferably shallow recesses 9, 10 and 11 formed inthe face of the lug, and 12 is a spring controlled pin which is mounted in the hole 5 of the lug 2 adapted to engage the shallow recesses 9, 10 and ll'of the lug 8.

When it is desired to lix the casing in a vertical position the pin 12 is adapted to enf gage the recess 9; when it is desired to fix the casing ina forward position the pin is adapted to engage the shallow recess 10 and when,it is desired to fix the casing in a rearward position the pin is adapted to engage .the shallow recess 11.

.which engages thevgear 21 and outside the casinga handle 26 1s provided designed to be fitted on theouter end of the shaft 18 and be used to wind the clock spring 22.

The shaft 17 is provided with a gear 21 having the rWella known clock operating spring 22 therein and provided with.- a ratchet 23 on its face and a pawl 24 is pivotedtdthe casing 1 and engages the ratchet.

The shaft 12 is provided with abevel gear 27 which engages a bevel gear 28 on a vertical shaft 29, mounted on the top of thel casing, anda bevel gear 30 on the upper end of the shaft 29 engages a bevel gear 31 on the shaft 32 which carries the fan 38.

In order to-slow down the speed of the fan, or stop it altogether a friction brake'34 is providedwhich comprises a friction wheel ordisk 35 mounted on the shaft 12 and a lever 36 pivoted to the casing 1 is adapted to be movedlaterally and abut and engage the side of the friction wheel 35. 0

The side of the wheel 35 or the side of the lever 36 may be provided with a covering of leather, rubber or other suitable. material to prevent Wear of the contacting parts and assist in making -a close contact.

` In order to retain or lock the lever 36 in .its proper relative position to the friction Wheel 35, ratchet teeth 37 are provided on the lower edges of the opening 3,8 in tle casing which are adapted to be engaged by the tooth 39 depending from the lever 36.

The operation is so obvious that I have not thought it necessary to describe it.

I do not Wish to be understood as limiting myself to the specific details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement, in

the adaptatin of the device to various conditions of use, without departing from the spirit and scope of my invention. and improvements. I therefore reserve the right to all such variations and modifications as properly fall within the scope of my invention and the terms of ,the following claim).

-What I claim is i i In a spring motor for fans, a base,\a closed casing the lowerportion of Which is directly pivoted to said base, means for securing said closed casing in angularly adjusted positions about said pivot, a train of gearing, a gear having a spring therein for actuating said train of gearing and means for winding the spring in said gear all located in said closed casing, a reduced closed cap at the upper portion of said closed casing,r a fan shaft and gears mounted Within said reduced closed 4cap operatively connected With'the train of gears in saiydclosed casing, a fan on said fan shaft located outside of the closed cap and casing and beyond the front faces thereof and a brake lever mounted in said lclosed casing.
